1.首先是父页面用window.open打开窗口
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm3.aspx.cs" Inherits="WebApplication17.WebForm3" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript">
function openChild() {
var k = window.open(‘WebForm2.aspx?id=110&id1=120&id3=130‘, ‘newwindow‘, ‘height=100,width=400,top=0,left=0,toolbar=no,menubar=no,scrollbars=no, resizable=no,location=no, status=no‘);
//window.showModalDialog("/WebForm2.aspx", "obj", "dialogWidth:335px;status:no;dialogHeight:300px");
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input type="text" id="txt10" name="txt10"/>
<input type="text" id="txt9" name="txt9"/>
<input type="text" id="txt11" name="txt11"/>
<input type="button" id="btn1" name="btn1" value="提交" onclick="openChild()" />
</div>
</form>
</body>
</html>
2.这是子页面
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="WebApplication17.WebForm2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript">
window.onload = function() {
var k = window.opener;
document.getElementById("txt1").value = k.document.getElementById("txt10").value;
var url = location.search;
if (url.indexOf("id3")!=-1) {
alert("url id3");
}
var theRequest = new Object();
if (url.indexOf("?") != -1) {
var str = url.substr(1);
strs = str.split("&");
for (var i = 0; i < strs.length; i++) {
theRequest[strs[i].split("=")[0]] = (strs[i].split("=")[1]);
}
}
};
function setFather() {
//给父窗口空间传值
var k = window.opener;
k.document.getElementById("txt10").value =
document.getElementById("txt1").value;
}
//设置返回到父窗口的值
function retrunValue() {
var s =
document.getElementById("txt2").value;
window.returnValue = s;
window.close();
}
</script>
</head>
<body>
<form name="abc" runat="server">
<input type="text" id="txt1" name="txt1"/>
<input type="text" id="txt2" name="txt2"/>
<input type="button" id="btn1" name="btn1" value="提交" onclick="setFather()" />
</form>
</body>
</html>
